Coaxial wire refers to a cable with two concentric conductors, and the conductor and shielding layer share the same axis. It can be used in fields such as cable television broadcasting, long-distance telephone transmission, short-distance connections between computer systems, and local area networks.

Coaxial wires can be divided into two basic types: baseband coaxial wires and broadband coaxial wires.
The shielding layer of the baseband coaxial cable is usually a mesh structure made of copper, and its characteristic impedance is 50Ω. This cable is used to transmit digital signals, and the commonly used models are generally RG-8 (thick cable) and RG-58 (thin cable).
The shielding layer of broadband coaxial cables is usually stamped from aluminum, and its characteristic impedance is 75Ω. This kind of cable is usually used to transmit analog signals. The commonly used model is RG-59. It is a standard transmission cable used in cable television networks. It can transmit multiple channels of TV signals in one cable at the same time. Broadband coaxial cables can also be used as the transmission medium of some computer networks.
Although coaxial cables have long been an important part of long-distance telephone networks. But in terms of transmission rate and coverage, there is no doubt that coaxial cables have fallen behind. Optical fiber, terrestrial microwave, and satellite that have made breakthroughs in all aspects will become the new mainstream in the future.
